I make burgers, steaks, and baked potato's all the time in mine. What I do is double wrap each burger, steak or potato in aluminum foil and throw it right into the hot coals. Let it cook about 3 minutes or so, flip it over with the poker for another 3-5 minutes and most times its done and ready to eat. Potato's take a little longer then the meat, but the taste can't be beat.
My grandfather used to make vegetable soup on his Fisher Papa Bear every week during the winter months on his. He was a very good cook!!
